Bluetooth not working on ASUS ROG Zephyrus G15 GA503QM-HQ019 with Ubuntu 20.04

I have just bought ASUS ROG Zephyrus G15 GA503QM-HQ019. It comes with AMD Ryzen 9 5900HS and NVIDIA RTX 3060 6GB.

I have a big problem. I have an Bluetooth Headset and Bluetooth is just not working on my laptop.

I have switched on Bluetooth settings in Ubuntu, nothing happens and when I close settings the switch goes off.

Looks like Ubuntu cannot detect Bluetooth module.

More about system:

• I have Windows as first system and Bluetooth works here perfectly.
• Ubuntu 20.04 LTS.
• Linux kernel is 5.13.13-051313-generic, installed via Ubuntu Mainline.
• Wifi works perfectly
• Card is MT7921

So, does anybody know the solution for this?

Also, NVIDIA driver isn't working well, so if the solution for BT issues is to move to a new distributive, be free to write the one that compatible with my hardware.
